Background

Every camera lens produces more or less severe image deficiencies. Even with the most rigid production methods these deficiencies can not be eliminated completely.
In general the following rules apply

• The smaller the camera‘s format the larger the deficiencies
• The wider the lens angle the larger the deficiencies

This implies that with proliferation of digital SLRs the phenomenon of image deficiencies had to increase and actually has increased. Existing products in the market confirm the need but from a professional perspective do not represent a satisfactory solution.

The Acolens Correction Method

The Acolens correction method is based on mathematical variance analysis in the areas distortion, vignetting and lack of focus toward the image‘s edges. In a first step so-called profiles are generated with the Acolens Reference Chart based on focal length and aperture of the lens. The software‘s algorithms then calculate the actual and desired values for the eventual correction of the profile. This profile correction process is then simply applied to any image taken with the according lense and focal/aperture settings.
